PUNIP.

SPECIFICATION forming part of Letters Patent No. 665,999, dated January15, 1901.

Application filed March 3l, 1900. Serial No. 10,951. (No muriel T LZZwhom it may concern:

` Be it known that I, ISAAC O. DAY, a citizen of the United States,residing at Ottumwa, in

the county of Wapello and State of Iowa, have invented a new and usefulPump, of which the following` is a specification.

My invention relates to pumps, and more particularly to that class ofpumps used in what are known as drive-wells, and has for 1o its objectto provide a pump of this class with means whereby the surplus waterabove the lower valve may be returned to the portion of the pump belowthe valve to prevent freezing.

It also has for its object to provide a `means whereby the lower valvemay be removed by means of the sucker-rod. n

With these objects Ain view my invention consists in the improvedconstruction and novel arrangement of parts of a pump, as will 2o behereinafter more particularly set forth.

In the accompanying drawings, in which the same reference-numeralsindicate corresponding parts in each of the views in which they occur,Figure 1 is a longitudinal sectional view of a pump embodying myinvention, and Fig. 2 is a detail view showing the manner in which thelower valve is removed by means of the sucker-rod.

In the use of what are known as drive- 3o wells it is very desirablethat means be employed for permitting the escape of the waterwhich isdrawn above the lower valve for the purpose of preventing the same fromfreezing and bursting the pipe. Heretofore it has been common to providethe pipe above the valve with a small outlet which will permit the waterto escape and be absorbed by the surrounding earth, a cavity beingsometimes formed at that point to assist in the opera- 4o tion; but thisis not desirable for many reasons. In other cases a pipe has beenextended downwardly upon the exterior of the main pipe whichcommunicates with the outlet; but this also is objectionable.

In practicing my invention I provide the outer end of the pipe 1,forming the driven well, with a casting 2, which is perforated to form achannel 3 from the top of the pipe l up into the barrel or cylinder 4 ofthe upper 5o portion of the pump. The lower end of the pipe is providedwith the usual perforated strainer or pointed cap, which is forced downthrough the earth in the usual manner until` it reaches the usualwater-bearing sand strata and through which the wateris drawn as thepump is operated. The channel through the casting is preferably curvedor extended to one side of the bore of the pipe l and is pro vided withan auxiliary channel 5, which extends into the portion of the castingdirectly above-the bore of the pipe 1 formed by the bend or curve in thechannel 3. A screwthreaded opening is formed in the casting below theinner end of the channel 5 for the reception of a small pipe 6, whichprojects down through the pipe 1 to below the water-level, so that itslower end is always immersed in the water. A branch pipe '7 extends froma small outlet-opening S in the side of the barrel down to the upper endof the auxiliary channel, so that any water remaining Within the pumpabove the outlet will gradually iind its way through the pipe '7,channel 5, and pipe 6 down into the source ot supply at the bottom ofthe well.

The barrel of the pump is secured to the casting 2 in any suitablemanner-eas, for instance, by means of screw-threads-and is providedintermediate its ends with a washer 9, to which a pipe l0 is secured, sothat it willA project down toward the casting a suitable distance.Secured to the casting at the upper end of the channel S-as, forinstance, by means of an ordinary screw-threaded nipple-is a valve-cage12, the upperend of which is provided with a screw-threaded perforation13, the threads of which are arranged reversely to the threads by meansof which the valve is secured to the casting. Extending down through thebarrel of the pump and through the pipe 10 is the sucker-rod 14, thelower end of which is provided with the ordinary cupped head or valve15. The upper end of the rod is secured to the handle 16 by means ofscrew-threads which correspond with the threads in the upper end of theIOO will draw the water up through both pipes as soon as it passes abovethe outlet 8, for the reason that the lower end of the pipecommunicating with said outlet is constantly loeneath the surface of thewater. In this manner the liability of the air entering through theoutlet to destroy the eciency of the pu mp to that extent is entirelyavoided and the objectionable features in connection with the use of apipe outside of the main pipe are avoided, and at the same time thewater is prevented from escaping around the upper portion of the pumpand causing waste and damage.

When it is desired to remove the lower valve without removing the lowerportion of the barrel, the upper portion of the barrel is removed andthe sucker-rod detached from the handle and inverted, and its upper endis screwed into the perforation in the top of the valve-cage.. As thesescrew-threads are arranged reversely to those by means of which the cageis secured in position, the continued rotation of the su er-rod/ willunscrew the cage from its position, when it may be withdrawn by theremoval of the sucker-rod. It can be replaced by the same process, whenthe upper portion of the barrel ofthe pumpv of a barrel connectedwiththe upper end thereof and provided with an outlet, and a smaller pipecommunicating with said outlet and extending down within thefirst-mentioned pipe to a point below the water-level, substantially 'asdescribed.

2. In a pump, the combination, with a pipe, of acasting secured to theupper end thereof, said casting being provided with a main and anauxiliary channel, the main channel communicating with said pipe, asmaller pipe communicating with the auxiliary channel and projectingdown through the first-mentioned pipe to a point below the water-level,a barrel secured to said casting and communicating with said main.channel, and provided with an outlet in communication with the auxiliarychannel, substantially as described.

8. Ina pump, the combination, with a pipe, of a casting secured to theupper end thereof provided with a main channel and an auxiliary channel,the main channel communicating with said pipe and having itsintermediate portion curved or bent to one side and the inner end of theauxiliary channel extending from the top of the casting into the portionof the casting formed by the bend in the main channel, a smaller pipecommunicating with the inner end of the auxiliary channel ata pointabove the upper end of the rst-mentioned pipe and extending down withinsaid pipe to a point below the waterlevel, a barrel secured to thecasting and provided with an outlet, and a branch pipe leading from saidoutlet to the upper end of the auxiliary channel, substantially asdescribed.
